Abstract

AbstractBackground: Dengue has emerged as a global public health problem, about 500,000 affected patients of 50–100 million cases will develop severe dengue infection. Therefore, early identification of severe dengue infection symptoms can save a patient’s life. The 2009 WHO dengue infection classification proposed seven warning signs to identify the risk of severe dengue. This study was conducted to predict the severity of dengue infection based on the number of warning signs.Methods: This was a diagnostic study conducted with a retrospective analytic observation of patients admitted to Adam Malik hospital with a diagnosis of dengue infection from January 2014–May 2016. The association between warning signs and severe dengue infection was analyzed using logistic regression. We also analyzed the sensitivity, specificity, positive predictive value and negative predictive value.Results: Of 140 patients who fulfilled the research criteria were collected from the medical records. The patients were classified as severe dengue (n=28) and nonsevere dengue (n =112). The warning signs that were associated with severe dengue were persistent vomiting (p<0.05, OR 31.9, 95%CI), fluid accumulation (p<0.05, OR 22.4, 95%CI), mucosal bleeding (p<0.05, OR 9.1, 95%CI), lethargy (p<0.05, OR 43.1, 95%CI). After analyzing the diagnostic tests, the combination of three or more warning signs showed that sensitivity of 92.9%, specificity of 78.6%, positive predictive value of 52%, negative predictive value of 97.7% was found to be associated with a severe dengue infection.Conclusion: The combination of three or more warning signs showed a high sensitivity and specificity for predicting a severe dengue infection.

The focus contained in this research is to determine the influence of Price (X1), Perceived Quality (X2), E-wom (X3), Promotion (X4), Trust (X5) and Brand Image (XA) on Purchase Intention (Y) . The research method is quantitative. This research uses smart PLS as the basis for testing. The population in this research is Indonesian people who have an interest in buying Kick Avenue products. In this research, the researcher used 7 variables which were measured with a total of 24 questions, so the total sample required for this research was 24 multiplied by 10, which means the total sample that will be used in this research is 240 Indonesian respondents. The findings can be summarized that the relationship between the variables Price , Perceived Quality , promotion , trust, brand image the Purchase Intention variable has a relevant influence. In contrast to the findings, it can be summarized that the relationship between the E-WOM variables the brand image variable does not have a relevant influence. Compared with the findings in hypothesis VII (Seventh), it can be summarized that the relationship between the E-WOM variables the Purchase Intention variable with brand image mediating does not have a relevant influence.
